Werewolf

Werewolves are a form of human that arose by a mircaculous combination wolf bites and everyone's favourtie plot device, radiation.

Not all werewolves are native american. They also don't usually have fan girls. In fact, the opposite is normally true. (See Collen Darkclaw )

Under certain conditions, they transform into wolf-men, with incredible strength and agility. They can also pass on their condition....through bites (if this was a surprise to you, you are either from another country, or have never talked to anyone).
